BA6220
GENERAL USE ELECTRONIC
GOVERNOR
DESCRIPTION
The UTC
BA6220
is a monolithic integrated circuit, developed for
speed control of general use DC motors.
LINEAR INTEGRATED CIRCUIT
DIP-8
FEATURES
* Wide range of working power supply voltage range
(V
CC
= 3.5V - 16V).
* Very large starting torque at the low voltage.
* Large permissible loss due to effective utilization of substrate
radiation.
* Usable for various DC motors by means of changing constants of
the external components.
SOP-8
APPLICATION
* Radio cassette tape recorders
*Pb-free plating product number: BA6220L
